Expansion of the invasive insect pest Corythucha arcuata (Say, 1832) (Hemiptera: Tingidae) in oak forests of Austria and Bulgaria
Abstract
The oak lace bug Corythucha arcuata (Hemiptera: Tingidae), native to North America, has already colonized millions of hectares of forests in Europe, Asia and Russia in recent years and continues to expand towards Central and Western Europe. Nymphs and adults suck on leaves and cause yellowing and premature leaf drop when trees are heavily infested. The aim of the project is to document the spread of this invasive species and to survey the current infestation of oak forests in Austria and Bulgaria. The data will be complemented by laboratory experiments on the biology and ecology of the oak lace bug, in particular generation development at different temperatures and mortality rates of overwintering imagines will be investigated. This information is critical for forecasting future damage trends. In addition, insects from the field will be examined for the presence of parasitoids and pathogens that can significantly dampen population development of the pest. A key aspect of the project is the mutual exchange of information and experience between the research groups of both countries, which will allow to fill knowledge gaps on the regulation of the population dynamics of this invasive species by abiotic (e.g. temperature) and biotic factors (e.g. natural counterparts).
